7 mm rem mag and ramshot grand

Got a winchester xpr 7 mm rem mag with factory 26 inch tube. I was doing some chronograph reading using 150 accubond I ran loads till I hit pressure backed off 1 grain no pressure but my velocity was was extreme 3376 fps . Has anyone else had this kind of velocity
What kind of powder are you using? I've had the same results using N560 powder
 
I've only used it in a 243 so far, and have good velocity, BUT I can't get enough of it in the case to reach pressure/max load using Hornady 103gr ELD-Xs. That said, what I can stuff in there gets me over 3000. It lists as about the same burn rate as H1000, but yet you generally use a few more grains of it for comparable loads. Scratching my head on that one. It's not the most dense of powders. That's what makes RL26 so good - SUPER dense!
 
My 7 weatherby is only 3300fps with factory ammo it blew my mind how much velocity it gained
76 fps is Mind blowing? Hmmmmm. I would expect nothing less reloading over using factory. Were you expecting to be slower? You loaded till you hit pressure....all factory are SAFE LOADED...well under pressure max for liability reasons.
